Abstract

Novel materials from Feldspar as clay material and KH2PO4(KHP) are prepared by grinding in a planetary ball millin a mechanochemical process, one of the most effective ways to synthesize slow-release fertilizers. In two paths,tests were carried out with (3) weight ratio of Feldspar: KH2PO4contents, at mill the incorporation of KH2PO4andthe liberation of K + and PO43−ions into solution were assessed at rotating speeds ranging from 200 to 700 rpmfor 2◦h, and at milling periods ranging from 1, 2, and 3◦h. Thermal gravimetric analysis (TGA), X-ray diffraction(XRD), Fourier transform infrared spectroscopy (FTIR), and ion chromatography (IC) were employed to analyze theproduced materials. The results confirmed that the mechanochemistry process is a sustainable chemistry methodto produce amorphous Feldspars containing KH2PO4. After dispersing Feldspar and KH2PO4in water for 24◦h,K+and PO43−ions were measured. Based on these studies, it has been demonstrated that intercalated Feldsparcould function as a carrier of K+ions and release PO34−ions as a slow fertilizer
